SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill guides teams to adopt test-driven development by formalizing a test-first workflow, reducing ambiguity and speeding feedback.

Core Features & Use Cases

  • Guided TDD workflow: Start with a failing test, write minimal production code to pass, and refactor with confidence.
  • Applicable to features, bugs, and refactors: Works across new work, bug fixes, and code improvements.
  • Real-world example: When starting a new feature, write a failing test for the expected behavior, implement minimal code to pass, then iterate until all tests pass.

Quick Start

Run the TDD cycle on a feature by first writing a failing test, then implementing minimal code to pass, and finally refactoring for clarity.

FAQPage Schema
What is the red-green-refactor cycle in test-driven development?▼

The red-green-refactor cycle in test-driven development is a workflow where you write a failing test, implement minimal production code to pass it, and then refactor the code for clarity with confidence.

How do I start writing tests first for a new software feature?▼

To start writing tests first for a new feature, write a failing test for the expected behavior, implement minimal code to make it pass, and iterate until all tests pass before refactoring.

Can I use a test-first workflow for bug fixes and code refactoring?▼

Yes, the test-first workflow applies to bug fixes and code refactoring across typical codebases by guiding you to write failing tests that define expected behavior before making minimal code changes.

Do I need a specific testing framework to implement test-driven development?▼

Yes, test-driven development requires an existing testing framework and the discipline to write failing tests first, then minimal production code to pass them before refactoring.

Why write minimal production code to pass a failing unit test?▼

Writing minimal production code to pass a failing unit test reduces ambiguity and speeds feedback by ensuring the implementation strictly adheres to expected behavior without unnecessary complexity.
